The current version can support 50,000 images, which is stated in the manual.

For very large projects, the alignment step can be split into several sub-projects for processing. The rest of the steps, can be processed by clustering.

Bug Reports / Convert whether K4 is enabled for the InPHO project
« on: October 30, 2021, 07:55:56 PM »
This issue has been raised for a long time, PhotoScan conversion to inpho project distortion coefficient is wrong.

It was not taken seriously by official engineers

Why is that?

I further verified this problem.

If it is an aerial camera with small distortion coefficient, At this time, K4 distortion coefficient will not be introduced.PhotoScan conversion results work normally. For example, leica, Feisi and other professional equipment.

However, PhotoScan will automatically reference the K4 distortion coefficient for devices with large distortion coefficient, and the result is wrong.

This has been a problem for years.

Bug Reports / Re: Import inpho camera POS and distortion coefficient

Hello Alexey Pasumansky

The currently converted parameters do not work properly. With reference to the project that pierced the control point, import or export the project, and then introduce the control point, the position of the predicted point should be very close to the position of the control point in the photo.

In practice, when PS imports the project of INPHO, the image at 1:1 shows that it is the wrong result of deformation.

Similarly, the import result is also wrong.

Bug Reports / Re: Ellipsoid conversion, elevation Z not calculated

Different models have different definitions of parameters. As long as there is one method, seven parameters compatible with PS can be obtained, which can properly solve this problem.

Current,version 1.7.4 pre support to Inpho 8.0.11 version, the new version of Inpho has not yet supported.  An error in importing POS is a compatibility problem of the project file format.

The distortion coefficient conversion has not been able to work normally.

If you import a successful project without aligning and adjusting again, the accuracy of the generated DOM is wrong.

I tried to import the inpho project, and immediately exported the Bentley CCCXML to check the accuracy of the control point prediction in the Bentley CCC, which was correct. Therefore, the question is whether PS allows direct use of imported inpho engineering production results.

The height read from EXIF is ellipsoidal height, which needs to be converted to normal height by introducing EGM. At present, there is no option to enable quasi-geoid in the fully automatic processing of the software. This is a very meaningful function.

Feature Requests / Cannot be adjusted to POS
« on: July 23, 2021, 09:33:15 PM »
Usually when optimizing the camera, parameters such as f cx cy will be checked.

If the control point and the Z of POS are not in the same coordinate system, it will cause a lot of trouble. You will find that f is optimized very small.

If you uncheck f, you will find that there is no optimization at all.

This reminds me of inpho, which spreads the residual of the adjustment into the x y z of POS, which effectively avoids the problem of control points and POS elevation z, which are not in the same coordinate system.

General / Re: Network processing 99% Too long
« on: July 23, 2021, 09:25:24 PM »
It still hasn't been solved. Distributed alignment is too painful.

I have come across two software that use nodes to adjust independently and then merge to achieve distributed alignment. Like PhotoMesh.

It is hoped that the future version can be improved.This will be a very competitive feature.

Bug Reports / Ellipsoid conversion, elevation Z not calculated
« on: July 23, 2021, 09:16:32 PM »
reproduction process,
a calculates the seven-parameter Bursa model
b selects the xyz coordinate system in ms,camera selects wgs84 ,input the seven-parameter
c converts pos to xyz and to check pos

There is no change in z, and z will change in the software that calculates the seven parameters.

Is it possible to add a matching seven-parameter calculation function and save the results as a prj file?

This problem has existed for a long time, usually we use distortion-free images, which have not been paid attention to.

Reproduce process

a export inpho prj
b open with inpho, import control point
c in the prickle interface, you will find that the image is deformed.

Bug Reports / Import inpho camera POS and distortion coefficient
« on: July 23, 2021, 09:01:13 PM »
I found one problems for POS

a The records in the pos and inpho PRJ imports are inconsistent, and the first line is omitted.

I found two problems for distortion coefficient:
a·Check camera parameters dialog box, all parameters are N/A
b.Multiple cameras or one camera has several sets of parameters (inpho self-calibration),Unable to recognize。

and 1.7.4 - Pre,There is a problem with the distortion coefficient conversion, which only needs K1-K3 P1-P2.

Hello RUVI7952, it is possible to share in another link, it becomes impossible to download outside of china from baidu without account.


I can only download, not upload. What can we do about it?

Can you leave your email and upload it for me?

General / PhotoScan AT Conversion to INPHO Tools 【Public】
« on: July 23, 2020, 09:13:09 AM »
I wrote a program to convert PhotoScan AT results into an INPHO project.

The only difference between the public version and my private version is that TiePoint and control point cannot be imported.

My approach has the following advantages:

1, support distortion(k1\k2\k3\p1\p2) transformation, you do not need to export undistortion image.
2. OPK conversion is supported. You can use the Match-AT initialization EO function.

Hope to improve your work efficiency.

Is it possible to add the ability to read Angle elements?

Bug Reports / "B1" Not involved in the operation
« on: May 20, 2020, 12:07:22 AM »
I hardly ever use B1.

for DJI 4 RTK

f = fy
k1 = k1
k2 = k2
k3 = k3
p1 = p2
p2 = p1
B1 =  fx / fy - 1, so I've defined B1.

After the photo is aligned, B1 doesn't change at all. I didn't fix B1, which I think is strange.
Usually, self-check will cause the parameters to change, but B1 has not changed.
